IMPROVEMENT IN MEASURING-FUNNELS.

TO ALL WHOM IT MAY CONCERNz- Be it known that I, JOHN H. ELWARD, of Mendota, in the county of La Salle, and State of Illinois, have invented a new and useful Improvement in Measuring-Funnels and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making part of this specification, in which Figure 1 is a perspective view, and

Figure 2 is a vertical section.

The same letters are employed in both the figures in the indication of parts which are identical.

' A is the body of theframe, the pipe of which may be closed by the valve B shutting upon a suitable valveseat so as to form a tight joint. The valve is attached to the rod C, which rises vertically through the centre of the funnel, having placed upon it fianges, D, which mark the various quantities desired to be measured. The upper end of the rod is fastened to the lever E, which is hinged to the edge of-the funnel opposite to the handle. The lever E crosses over the funnel andpasses through the handle F at F, where there is a longitudinal slot cut transversely at each end, so as to hold the lever in position. The length of the rod 0 should be so regulated that wh'eh the valve is closed the lever E should be bent in order to enter the recess-in the lower end of the slot F, the elasticity of the lever serving as a spring to hold the rod in place. This valve should be closed only when the funnel is to be used, so as not to injurethe elasticity of the lever by an unnecessary continuance of thestrain. I

What I claim as my invention is not the use of the valve nor device for measuring, for these have been used in funnels before; but what I do claim, and desire to secure by Letters Patent, is

The combination of the valve B, rod 0, lever E, and slotted, handle F, said parts being so constructed and arranged that the lever E, when the valve is closed, shall form a spring, by the tension of which the parts are held firmly in position, substantially as set forth.

In testimony whereofI have signed my name to this specification in the presence of two subscribing witnesses.

' JOHN H. ELWARD.
